She said: "Going so much over the speed limit is taking a blatant risk with lives on the road. A fine of a few hundred pounds for someone who earns thousands a week is not really a deterrent.

"We would like to see anyone going so significantly over the speed limit to be treated as committing a much more serious offence and prosecuted for careless or dangerous driving, rather than speeding, and face an automatic ban."

Andrew Howard, head of road safety for the AA, said: "Driving at over 100mph does not mean an automatic ban, but the guidelines suggest that it should. The only guideline laid down for the courts for speeding offences is a maximum fine."
